Mariposa LPOE Environmental Review

The $187 million modernization and expansion of the nation’s third-busiest land port achieved LEED® Gold certification for its use of energy-efficient technologies, including solar-powered domestic hot water, advanced lighting and building automation systems, a rainwater harvesting system, as well as recycled content material selections and low-maintenance finishes that are used throughout the port's design.

The final Environmental Assessment (EA) was published on June 12, 2009 and the Finding of No Significant Impact a month later. The EA received input from local governments such as the Arizona Department of Transportation as well as the mayor of Nogales and others along with EPA and local businesses. It was completed by AZTEC Engineering and is available in the NEPA Library.
